One of the new astrophysical phase spaces is exploring sky in the optical (320 nm – 650 nm) range within millisecond to nanosecond timescales known as ultra-fast astronomy (UFA). For this purpose, we developed our own customized readout system for silicon photomultiplier (SiPM) to scan the sky as fast as possible. SiPMs are capable of single-photon detection in the visible light range. The developed readout system for these detectors consists of 16 channels of 14-bit data logging. Each channel includes a 50-dB gain pre-amplifier, signal shaping circuits, analog front end, analogue to digital converter and Xilinx UltraScale+ MPSoC board for data-logging. The results of our readout system show that, scans can be done with 16 ns time frame and a power consumption of 250~mW per channel.
